The Grey-throated Sunbird (Anthreptes griseigularis) is a species of bird in the Nectariniidae family. It is found in a wide range of semi-open wooded habitats in the northern and eastern part of the Philippines. It is often considered a subspecies of the Brown-throated Sunbird, but the two differ consistently in measurements and plumage, and there is no evidence of intergradation between them.[1] It has not been rated by BirdLife International (and consequently IUCN), but is generally common and therefore unlikely to be threatened.
